The present invention relates to a set of lens-assembly parts for a protective goggle and to lens assemblies formed therefrom.
Eye protection in sports, industry, military and police activities typically involves use of a goggle or lens assembly, often in association with a face mask in order to fully cover the face and the sides of the user's head. To prevent eye injury from impact by projectiles, splashed or projected liquids, and other flying objects, the lens is securely mounted in such assemblies to prevent dislodgement or disengagement from the assembly. Goggles or goggle-mask systems combinations are difficult to disassemble for changing lenses or for cleaning. The present invention addresses this problem, and provides a set of lens assembly parts and of assemblies therefrom for easy assembly/disassembly for replacing and/or cleaning the lens, for the replacement of other portions of the assembly, and for cleaning the assembly.
The invention is directed to sets of lens assembly parts and lens assemblies formed from the sets. In one aspect, a set of lens assembly parts comprises a base which is shaped to fit over the eyes and which has a lens receiving portion and a frame shaped for registration with the base. The base as well as the frame each comprise opposite temple portions. A lens, which is shaped to be positioned and secured between the base and the frame, may be included in the set. The opposite temple portions of the frame and the base comprise fasteners for tensioning the base against the frame and for securing the lens. The fasteners are inserted in registration openings which are formed in the frame and the base, and in which openings protrusion-retention elements (e.g. twist locks) are positioned. A version of the set of assembly parts contains a mask, which after assembly, is attached to the base. The set may contain a strap sized for fitting a lens assembly, which is made from the set of parts, to the head of the user.
Subjects of the invention further include lens assemblies formed from various combinations of lens-assembly parts.
In one aspect, the subject invention involves a set of parts for forming a lens-assembly. Included in the invention are different lens-assemblies formed from the set of parts.
The set of lens-assembly parts of the invention involves a base 15 which is formed of rigid or flexible plastic (FIGS. 1 and 2). The base is shaped to fit over the eyes. Formed in the base is a lens receiving portion 30 which is configured for receiving a lens 20 (FIG. 3). This lens receiving portion 30 defines a lens opening 35. Opposite temple portions 40 of the base extend rearward from the lens opening, and terminate in base terminal sections 45. A frame 25 (FIG. 4), also formed from rigid or flexible plastic material, is configured for mating alignment or engagement with the lens 20 to be positioned in the lens receiving portion 30 of the base. An opening 50 in the frame 25 registers with the lens opening 35 in the base 15. Opposite temple portions 55 of the frame extend rearward from the frame opening and terminate in frame terminal sections 60. In the lens assembly 10 (
When the set of lens-assembly parts is in operation, lens 20 is positioned or sandwiched between the base 15 and the frame 25 (FIG. 6). The lens 20 has a configuration which fits the lens receiving portion 30. The inner side 51 of the frame 25 is engaged with sections of the outer side 67 of the periphery 65 of the lens 20, namely, respective opposite brow 70, temple 75 and cheek 80, and nose 85 sections.
In a version of the set of lens-assembly parts, the opposite terminal regions 62 include fasteners 100. When releasably tightened or locked, the fasteners tension the lens receiving portion 30 of the base 15 and the inner surface 51 of the frame 25 against the inner and outer surfaces of the lens periphery 65, thereby fixing or clamping or otherwise securing lens 20 between the base 15 and the frame 25.
In one set of embodiments, the fastener 100 cooperates with registration openings 90 formed in the terminal section 45 and 60 of the frame and in the base. A coupler 105 extends into and about the registration openings 90 (FIG. 7A). Typically coupler 105 includes a protruding element 110 and a retention element that engages with registration openings 90. Examples of couplers include, but are not limited to, twist lock cams 97 (a cam inserted through registration opening 90 and fitting into a cam channel formed about the side of registration opening 90 that is situated on the inner side of base 15, (FIG. 6)). Other protruding elements 110 can be selected from bolts, rods, dowels, lugs, pins, rivets, and screws, while a retention element is selected for mating engagement with the protruding element. Retention elements are well known to those in the art, and include, without limitation, tightenable collars, annular members for frictional and/or snapping engagement with protrusion elements, and threaded openings. The fastener may also be formed in whole or in part from hook and loop materials positioned on or about the fastener in the terminal regions.
Preferred versions of the set of lens-assembly parts involve fasteners which the user can easily unfasten. Easy and quick unfastening results in easy, quick, and convenient disassembly of a lens assembly of the invention and removal of the lens 20 for cleaning or replacement, which is advantageous to the user. The base and frame can be easily cleaned and adjusted. In particular, quick and easy disassembly of the lens assembly allows the user to clean the peripheral portions of the lens 20, the lens receiving area of the base 15, and the inner surface 51 of the frame 25. These areas collect solid or liquid debris that tend to corrode, craze, crack or otherwise weaken a lens, frame or base, and which are difficult to access for cleaning in conventional lens assemblies. Additionally, quick and easy disassembly allows replacement of the frame 25 with frames of other shape, size, color, design or ornamental design provided that a replacement frame is structured for registration with the base unit as described herein.
When fastener 100 comprises a twist lock cam 97, slots of matching size to twist lock cam 97 are formed on surfaces of the frame 25 and base 15, the slots being in juxtaposition to define registration opening 90 and to secure lens 20 between the frame 25 and the base 15. Twist lock cams 97 and registration openings 90 are sized and positioned to correspondingly mate into sufficiently tight engagement (snapping engagement) to secure the lens, typically with a ¼ turn of protuding element 110, yet be subject to easy unsnapping by the user with a reverse ¼ turn. Fastener 100 and registration openings 90 may be positioned in the terminal region or in the regions or in the region of the base 15 and frame 25 which fit over the user's brow, cheeks, nose or any combination of those regions or sections of the base 15 and frame 25 so long as they arranged and sized for snapping engagement and easy unsnapping. Continuous or discrete areas of hook and loop fabrics can be positioned on surfaces of the frame 25 and base 15 which will be in juxtaposition for securing lens 20 between the frame 25 and the base 15. Interengagement of the hook and loop surfaces achieves securing of the lens 20 between the frame 25 and the base 15.
Another embodiment of the set of lens-assembly parts involves a fastener which is a clamp or sliding clip which fits about the terminal portions of the opposite temple portions of the base 15 and 25. A fastener takes the form of a flexible band which wraps about the opposite temple portions and tighteningly engages, securing the lens 20 between the base 15 and the frame 25. Hook and loop material disposed on a band provides surfaces on the band for interengagement and tightening. It is preferred to use a wrapping fastener that is easily untightened.
Another version of the set of lens assembly parts further comprises a strap 120 (
It is understood that fastening the frame 25 to the base 15, which sandwiches the lens 20 into a secure position, is achieved by one or a combination of the above-enumerated structures and devices, and that the invention is not limited to embodiments which do not comprise more than one of the above so enumerated structures and devices.
Another embodiment of the set of lens-assembly parts further comprises a mask 125 (
Methods of molding plastics are well known in the art. One method of making a mask comprises the use of materials having more than one hardness and shaped by using a two-shot injection molding process, wherein both the harder and softer materials are sequentially injected in the same mold. Two-shot injection molding processes are known in the art, and thus will not be described in detail. During the hardening of the rigid plastic and rubbery materials in the two-shot molding process, a chemical bond is formed at the junction of the two materials, thereby permanently bonding the two materials together. This type of molding process provides for ease of manufacture, and further provides a long lasting construction. The manufacture of the set of lens-assembly part or lens assembly of the invention is not limited to the molding procedure described above.
The base 15, frame 25 and lens 20 are advantageously inter-engaged through a series of tabs 130 and slots 135 formed therein, and which are sized and positioned to correspondingly mate into engagement (
As shown in
The set of lens assembly parts may further include a layer of material 186, for instance, foam, for cushioning and/or absorbing sweat, the layer being mounted on the inner side of the base 15 (FIG. 10).
